Positive and Negative Charges

The two types of charges are called positive and negative.

• True

• False

Objects with the same type of charge will attract one another.

• False

• True

This is not an accurate way to say this. The object is not "somewhat charged." It is still completely neutral. We will discuss this more in class.

For an object to have a neutral charge, what can we conclude about the positive and negative charges?

• There are more positive charges than negative charges.

• The object has the same number of positive charges as negative charges.

If an object is charged, what can we conclude about the charges in it?

• The number of positive charges is greater than the number of negative charges.

• The number of positive charges does not equal the number of negative charges.

What happens if you put two positively charged objects next to each other?

• They move toward each other

• They move away from each other

• They don't move at all

How is it that a charged object can attract a neutral object?

• The charged object gains neutrons

• The number of neutrons are reduced by one half

• The neutral object becomes "polarized"

What do you think will happen between the two balloons?

• The like charges cause the balloons to move toward one another

• The like charges will cause the balloons to repel one another
